RouterBOARD – Connecting an external antenna

The external antenna can be connected to the RouterBOARD RB751G-2Hnd via the MMCX connector at the front:

The part that you need can be found here. You can either connect the antenna to the MMCX connector and leave it dangling or you can actually fit it into the casing, which is extremely easy to do. To fit it into the casing take the RouterBOARD casing apart with a flat head screwdriver from the bottom. Once apart you will notice the cover which can be peeled off revealing four slots:

Simply choose a hole to connect the antenna to and push out the slot. Carefully put the sticky cover back on and cut out the hole with a knife or screwdriver:

It doesn't need to be neat as the antenna will slide over the edges. Once you have cut the hole in the cover simply feed the antenna cable through hole and back out the antenna slot hole and connect to the MMCX connector. Replace the bottom of casing and ensure the antenna is fitted securely into the slot:

To enable the antenna log into your RouterBOARD and go to Wireless and then the Interfaces tab. Double click your wireless interface and select the HT tab and set the Antenna Mode to be Antenna B:
